Installation help for ubuntu 14 x64

hi
I am new in QT.
I have a device name ARM Tiny6410 and the installation guide in chines language. i am confused because i have a lot of error and lot of question:
1: at first my question is : Is qt-everywhere-opensource-src-4.7.0 for 32 bit , ok for 64 bit ubuntu os?(OR i should install ubuntu x32?)
2: is it true: first i should install qt-everywhere-opensource-src-4.7.0 for compiler and the install qt creator?
3: what is qt-sdk-linux-x86-opensource-2010.05.1.bin? and for what?
4: I have this error when i install qt-everywhere-opensource-src-4.7.0 in my Ubuntu X64 :

The target system byte order could not be detected! Turn on verbose messaging (-v) to see the final report. You can use the -little-endian or -big-endian switch to ./configure to continue.

note:i repeat this code to-wise : ./configure ..
